one of the best things I have learnt is that when you want to reference the "built in" led on the Arduino the best way to do that is using "int led = LED_BUILTIN;". "LED_BUILTIN" just references to the built in LED. yes ik you can use pin 13, but this method makes sure that the led will light up on any (most) Arduino.
One question : This means main loop will resume only after while loop is completed or loop will be looping at microcontroller speed each time coming across while() and evaluating the condition ?
Hey, I'm trying to make a pwm and frequency counter that when it finds the desired frequency and duty cycle you press a button to stop the counting but remain transmitting at the frequency and duty cycle it stopped at. Also a back button and forward buttong would be desired to fine tune. I made the counter already but I have no control over it I have no idea how to interrupt the For loop. Any ideas?
Hello dear Can you help me to solve this I have 4 IR sensor When first sensor gives signal to aurdino for 1 sec only, after 2 sec our relay is on for 1 sec and then off And these all happened with all 4 sensor and 4 relays
what does toggle state do in the code and if i wanted to do a buttonState on a analog pin for a button on a LCD shield, is this how i would code it? buttonState = analogRead(btnSELECT);
Why use "=!" instead of "!="? Is this the logic behind the different operators?: toggleState NOT equal to toggleState and toggleState equal to NOT toggleState
Thumbs up for the content. However thumbs down for the size of the written code on the screen. Who on earth can see the wrighting if one watches the video on a mobile device, such us a tablet? Let alone watching it on a phone!. Really not usable. The text size should be about 5 times bigger than it is now for someone to see it without using a magnifier glass.

I love this guy! Thanks!
Been trying to get a while loop to work with a hall sensor but it won't leave the loop when the condition becomes false.

2:44 it's easy to add digitalRead inside the while loop condition instead of checking it through a variable.
I want to send some text to arduino to stop one condition and send another text to start another (if condition) could u make a video for that....
what does toggle state do in the code and if i wanted to do a buttonState on a analog pin for a button on a LCD shield, is this how i would code it? buttonState = analogRead(btnSELECT);
Im learning a lot here, so thx :-) but at 2:48...... "So, we're checking the button here" *points at screen off camera*. Just made me giggle ;-)
very nice... this would be be great with a switch-case to pick different while loops.. 🤔 thanks a lot. 🙂
how can i use interrupt with ultrasonic
how to beeak a loop?
Hi there.. Can I have I while loop in a function?
yes you can!!
Why use "=!" instead of "!="?
Is this the logic behind the different operators?:
toggleState NOT equal to toggleState
and
toggleState equal to NOT toggleState

I don't know. Maybe use a computer then? That's your problem. Font size is large enough.
There is a supplemental webpage link in the video info section. It may help.
bruh i can see it just fine on my iphone, you probably just have bad eyesight lmfao
